A pseudo-resilient bumper or shield attachment for attaching a bumper or shield to a vehicle is disclosed. The attachment is made up of a vertically extending elastically resilient counter-fitting having one end attached to the chassis of the vehicle and another end to which an inelastically deformable energy absorbing block is attached. The energy absorbing block is attached between the vertically extending counter-fitting and the bumper or shield, and includes collapsible energy absorbing thin walled partitions extending perpendicular to the resilient counter-fitting.

Bumper attachment apparatus, in particular for automobiles

An elastic guard brace for attaching bumpers to an automobile is disclosed. The brace consists of a relatively thick elastic member which is connected between the bumper and the automobile and is oriented so that the direction of its elasticity is parallel to the direction of a force acting on the bumper. At least one inelastic member is positioned within the elastic member and is oriented parallel to the direction of the force acting on the bumper so that it can buckle in an inelastic manner and absorb energy upon impact. The elasticity of the elastic member minimizes the inelastic deformation of the elastic element and returns the bumper to its original position.

Elastic guard braces for attaching bumpers to automobiles

A composite bumper structure is made up of an elongated molded bumper section, molded attachment lugs and energy absorbers. The bumper section is integrally molded with the lugs and both contain elongated reinforcement fibers. The energy of a collision is absorbed both by the deformation of the energy absorbers and the elastic deformation of the lugs. The bumper section may also support a stylistic facade.

Bumpers or shields for the protection of automobiles

The energy absorbing device for use as a composite bumper on a vehicle comprises a deformable unit providing a constant energy absorption, the unit being disposed in contact with a resisting structure and a flexible shield, and consisting of a number of energy absorbing members, each energy absorbing member being formed by the juxtaposition of a plurality of elongated hollow members having different lengths. Provision is made within the energy absorbing device of sections having an increasing impact resistance as the impact stress causes the energy absorbing device to be crushed, the stiffness of the energy absorbing device being thus enhanced as a function of the driving in thereof.

Energy absorbing device

This invention relates to an energy absorbing device intended to be used as a composite bumper. Said bumper comprises an energy absorbing beam, a deformable unit comprising at least two energy absorbing members located between the beam and the vehicle chassis, said beam being supported by said members, and a flexible shield wrapping either both aforesaid constituting units or a portion thereof.

This device for improving the safety of automotive vehicles comprises a structure adapted to be fitted in the lateral doors of the vehicle between the main panels thereof, said structure consisting of a sleeve member secured parallel to said panels in the direction of travel of the vehicle and anchored to the vertical edges of the door, and comprising a core with a peripheral winding made of glass yarn impregnated with resin and tensioned, the proportion of the component elements being 50 to 80 percent and preferably 70 percent of glass yarn, the balance consisting of resin.
